Cisco ASR 1000 Series Routers
The Cisco ASR 1000 Series Aggregation Services Routers are the next generation Cisco midrange router
products. The Cisco ASR 1000 Series Aggregation Services Routers use an innovative and powerful
hardware processor technology known as the Cisco QuantumFlow Processor. The following are the
Cisco ASR 1000 Series Routers:
• The Cisco ASR 1006 Router is a 12-SPA, 6-rack-unit (RU), hardware-redundant chassis with two
Embedded Services Processor (ESP) slots, two Route Processor (RP) slots, and three SIP slots.
• The Cisco ASR 1004 Router is an 8-SPA, four rack-unit (RU) chassis with one ESP slot, one RP
slot, and two SIP slots.
• The Cisco ASR 1002 Router is a 3-SPA, 2-RU chassis with one embedded services processor slot
that comes with the route processor, Cisco ASR 1000 Series Shared Port Adapter Interface
Processor (SIP), and 4 Gigabit Ethernet ports built in. For more information about the type of
connectors and cables used by the 4-port Gigabit Ethernet built-in SPA, the Cisco ASR 1000 Series
Aggregation Services Routers SIP and SPA Hardware Installation Guide.
• The Cisco ASR 1002-F Router is a one half-height SPA, 2-RU chassis. The embedded services
processor, route processor, and SPA interface processor (SIP) are integrated with the chassis. In
addition, 4 Gigabit Ethernet ports are built into the chassis.
• The Cisco ASR 1013 Router is a 24 half-height shared port adapters, 13-RU chassis that can hold 6
SIPs and provides superslots (more height and power) for the Cisco ASR1000-RP2s and Cisco
ASR1000-ESPs. The Cisco ASR 1013 Router is designed with two zones (Zone 1 and Zone 0) for
redundancy and superslot spacing. The Cisco ASR 1013 router has four 40G slots and two 100G
slots.
• The Cisco ASR 1001 Router is a one rack-unit chassis that offers a compact form factor router that
satisfies customer demands such as low power consumption and decreased usage of rack space. The
Cisco ASR 1001 Router has the route processor, embedded services processor, and SIP integrated
within the chassis with one half-height SPA slot.
• The Cisco ASR 1002-X Router is a 3-SPA, 2-RU chassis. The embedded services processor and
route processor of this router are integrated in the chassis. There are six small form factor pluggable
(SFP) Gigabit Ethernet ports. Depending on the Cisco software license that you install, the router
can provide a forwarding bandwidth of 5 Gbps, 10 Gbps, 20 Gbps, or 36 Gbps.
For the single-route-processor Cisco ASR 1000 platforms (Cisco ASR 1002, Cisco ASR 1002-F, Cisco
ASR 1002-X and Cisco ASR 1004), the route processor has a dual Cisco IOS Software option that allows
these routers to use Cisco IOS software redundancy, Cisco high-availability features, and Nonstop
Forwarding (NSF). Single-route-processor Cisco ASR 1000 platforms do not support ISSU upgrade or
downgrade. Instead sub-package software upgrade is supported only if the router is running in
sub-package mode.
Note The Software Redundancy feature requires the router to have 8 GB of DRAM memory.
The Cisco ASR 1000 Series Routers run Cisco IOS XE Software and introduce a distributed software
architecture that moves many operating system responsibilities out of the IOS process. In this
architecture, Cisco IOS, which previously was responsible for almost all of the internal software
processes, now runs as one of many Cisco IOS XE processes while allowing other Cisco IOS XE
processes to share responsibility for running the router.
